I broght them because they are cheap and you can use them whenever you like, as many times a day that you like without feeling guilty. Mine were costing between 20cents and 1.00 online, so I sometimes used two a day from 8 DPO onwards. And thought "so what".

They worked for me too. I got my current positive at 10 DPO. It was feint but there, and it got darker over the next few days.

They do tend to show "evaporation lines" a lot, however these are grey not pink and once you work out what these look like... the positive pink line (even if feint) is obviously different. I mean if worst comes to worst you can always wait a day and buy a chemist test for $10 when you think you see a pink line. This will still save you money.

I loved the ebay ones. It freed me up to test, test, test... without guilt. Which although I know does not suit everyone, really worked for me.
